Constructed with a durable and wind resistant 600D poly outer shell, PrimaLoft Gold Eco 400 gm insulation, and zippered vents. A technical handlebar attachment system includes a foam donut that seals the handlebar and cable closure, while also keeping each pogie in an upright position. Water-resistant zipper vents on top and bottom provide temperature regulation when it gets too warm, and an inner pocket makes stowing extra food and gear simple and accessible.
